To oZZ whom it may concern:

Be it known that I, GEORGE T. lVILLrAMs, a citizen of the United States,residing in the city and county of Denver and State of Colorado, haveinvented certain new and useful Improvements in Matrix-Bars forType-Casting Machines; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the artto' which it appertains to make and usethesame, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

My invention relates to improvements in matrix bars for type castingmachines.

The subject matter of this invention is divided out of my formerapplication, Serial No. 763,968, filed April 28, 1913, and entitledImprovements in type setting and casting machines.

In. my present construction, each matrix bar carries a number of matrixmembers, these members carried by each bar containing in the aggregatethe entire set of characters employed in printing, and correspondingwith those indicated on the keyboard of the machine with which the barsare used. The number of matrix bars necessary in a machine adapted'tohandle them, needs to be equal only to the number of letters orcharacters employed in the longest line which it may be desired to cast.This greatly simplifies the construction as compared with one in whichthere is adistinct matrix for each character employed as in the wellknown Mergenthaler type of machine.

The invention also includes a matrix bar having a plurality of fonts ofmatrix characters.

Having briefly outlined my improved construction, I will. proceed todescribe the same in detail, reference being made to the accompanyingdrawings, in which is illustrated an embodiment thereof.

in this drawingFigure 1 is a side elevation in detail illustrating oneof the matrix bars. F Qis a front view of a series of such bars inassembled. relation. 7 Fig. 3 is a fragmentary view showing a number ofmatrix bars in; assembled relation for easting a line of type, the moldbeing indicated ters in the opposite edge.

by dotted lines. Fig. 4 is a face view of a matr x bar having aplurality of fonts of matrix characters. Fig. 5 1s a view illustrating amatrix bar operatively equipped forutilizing a plurality of fonts ofmatrix characters of different faces or styles. This view also showsmeans cooperating with such a bar to utilize such characters.

The same reference characters indicate member 28 is provided with atooth 36 which is employed in arresting the downward movement of the barwhen employed in a type casting machine. This part 31 is com posed ofmembers 32 upon which the matrix characters are formed. Hence, the parts32 may be termed matrix members and are separated by parts 33 whichtogether with the parts 80 preferably consist of thin, light metalmaterial whereby the structure which forms a support for the matrixmembers 32 is suiliciently yielding to permit the matrix members whenassembled in operative relation for casting the'line of type, to moveout of vertical alinement with the other portions of the matrix bar. Itshould be explained that these matrix members 32 are of dilferenthorizontal thicknessesas best illustrated in Figs. 2 and 8. Eachmatrix'member has a series of notches formed on one edgethereofcorresponding in number with the charac- In these views, theupper matrix members are shown of the proper thickness for two pointtype, the members next below being of the proper thickness for fourpoint type, while the lowermost members are of the thickness for sixpoint type. Hence, it will be understood that when these diflerentmembers 32 are arranged in assembled relation and properly clamped toconform to the length of the line of type, it will be necessary forportions of the part 31 of the' matrix'ba r 17 to move out of the planeof the other portions of the same'bar. For this reason, the spring parts'38 separating'the matrix mempart 31. In order to permit the aforesaidmovement, the parts 30 are movably connected at their upper and lowerextremities with the rearwardly extending parts 29 and the parts 30'areslotted as shown at34 and connected with the parts 29 by means of pins35. It is evident that this constructionwill permit a limited degree oflateral movement of intermediate portions of the part 31 of the matrixbar. These matrix bars are well adapted for use with a machine of thecharacter set forth in my aforesaid application, but it must beunderstood that they may be employed at least so far as the broadinvention is concerned, with various other constructions.

' Each of the matrix bars 17 carries a space band 89 vertically movableon the lower spring part thereof, and when the matrix members 32 whosecharacters are to be utilized in casting the line of type'or" assembled,preparatoryto the casting operation, all of the space bands 89 of thevarious bars are in positions below the series of matrix members 32assembled in front of the mold characters. in print ng trade parlance afont is a com- 88. The first act for completing the casting arrangementof the matrix members 32 after they have assumed their positions infront of the mold, is to clamp these members 32 of the series from theopposite ends in order to bring the series of matrix members into aspace exactly equal with the lengthof line of type to be cast. The nextstep is to actuate the space'bands 89 whereby they shall be caused topass between the matrix members 32 assembled in operative relationwhereby the said members shall be properly spaced for dividing the wordsof the line of type to be cast. This upward movement of the vari ousspace bands which are wedge-shaped may be accomplished through themedium of any suitable mechanism and consequently alined horizontallywith the inner extremity of the opening of the mold which fits tightlyagainst the matrix members.

This invention includes a matrix bar having a plurality of completefonts of matrix It maybe well to explain that plete set of charactersrequired for printing,

including upper and lower case letters, fig- This is also true of theupper and lower portion 30 of each" 207 being also slightly three fonts.The bar is broken away, however, as it is deemed lmpracticable andunnecessary to illustrate the three complete fonts of characters, asthis would ordinarily necessitate the showing of 270 characters, asabove indicated. The drawing does, however,illustrate a matrix barwhich, when unbroken or complete, would contain three complete fonts ofcharacters,that 1s, a

complete font of roman, a complete font of italic, and a complete fontof boldface type, all on one matrix bar or member.

. In the construction illustrated in Fig. 5 of the drawing, a portion ofa type castingmachine is illustrated of the character disclosed in mysimultaneously pending application, Serial No. 763,968, in whichassembly pins 38 are arranged to. be'projected rearwardly at differentdistances by operating levers 4:0, 7 7

an adjustable spindle 204 being mounted in the frame and provided on oneside with a projection 205. When this spindle is so adjustedthat its camor projection is in the positlonshown 1n dotted lines in th1s view,

the rearward movement of the leverarms 40 1S limited, whereby therearward movement of their fingers 47 is correspondingly limited. Hence,when the spindle 204 is in the indicated in this figure. In this form ofconstruction, the tooth 36 of the matrix bars .is notched, as shown in206, whereby two supporting faces, designated 20' 7.and 208,respectively, are formed, the face 207 being slightly forward of theface 208, the face the face 208. V V

The object of this form of'construction is to make it practicable tosupport the matrix bar in position to utilize either of two adjacentmatrix characters where one is arranged V .directl above the other asfor instance, re-

ferring to Fig. 4, the roman character or the bold face character of amatrix bar having a plurality of matrix characters of different faces,or styles. If the pin 38 is projected by a lever arm 40 whenthe spindleis'in the dotted line position in Fig. 5, the rear extremity of the pinwill be in position to stop the downward movementof the matrix bar moreelevated than spindle is in the two different positions, is p when theface 207 of the tooth engages the .face 209 ofthe pin, whereas if thepin is prohigher elevation than when the face 207 engages the pin.Hence, if it is desired to utilize the lower matrix character of twodifferent faces or styles, the spindle'QOi will be moved to occupy thefull line position, whereby thepin 38 will be projected rearwardly toits limit of movement, and consequently stop the matrix bar in the moreelevated position, whereas, if it is desired to utilize a matrixcharacter next above of the two under consideration, the spindle will beturned to the dotted line position, so that the assembly pin shall beprojected to engage the face 207 of the tooth 36 of the correspondingmatrix bar.

lVhile provision is made by the disclosure in Fig. 5 for utilizing twocharacters only of different faces or styles, or for handling a matrixbar having two fonts of characters, it is evident that by adding anotherface to the tooth 36 and placing the same onematrix-space lower than theface 208, provision will be made for supporting the matrix bar inposition to utilize the italic A, for instance, referring to Fig. i. Inthis way, it is evident that means may beprovided for utilizing a matrixbar having any number of fonts of typographical characters without inany way departing from the spirit of the invention.
